I have an array of song titles, coming from this subreddit, looking like this:
[
"Lophelia -- MYTCH [Acoustic Prog-Rock/Jazz] (2019)",
"Julia Jacklin - Pressure to Party [Rock] (2019)",
"The Homeless Gospel Choir - I'm Going Home [Folk-Punk] (2019) cover of Pat the Bunny | A Fistful of Vinyl",
"Lea Salonga and Simon Bowman - The last night of the world [musical] (1990)",
"$uicideboy$ - Death",
"SNFU -- Joni Mitchell Tapes [Punk/Alternative] (1993)",
"Blab - afdosafhsd (2000)",
"Something strange and badly formatted without any artist [Classical]",
"シロとクロ「ミッドナイトにグッドナイト」(Goodnight to Midnight - Shirotokuro) - (Official Music Video) [Indie/Alternative]",
"Victor Love - Irrationality (feat. Spiritual Front) [Industrial Rock/Cyberpunk]"
...
]
I am trying to parse the title and artist from them but am really struggling with regex.
I tried splitting it using "-"
but it's really annoying to only get the artist afterwards.
I tried using regex too but I can't really get something working properly.
This is what I had for the artist: /(?<= -{1,2} )[\S ]*(?= \[|\( )/i
and this for the title: /[\S ]*(?= -{1,2} )/i
.
Every entry is a song title. Before the song title could be the song's artist followed by one or two (or maybe 3?) dashes. Then the genres could be added in square brackets and/or the release date in parentheses. I do not expect perfect accuracy, some formats might be weird, in those cases, I would rather have artist
be undefined than some strange parsing.
For exemple:
[
{ title: "MYTCH", artist: "Lophelia" },
{ title: "Pressure to Party", artist: "Julia Jacklin" },
{ title: "I'm Going Home", artist: "The homeless Gospel Choir" },
{ title: "The last night of the world", artist: "Lea Salonga and Simon Bowman" },
{ title: "Death", artist: "$uicideboy$" },
{ title: "Joni Mitchell Tapes", artist: "SNFU" },
{ title: "afdosafhsd", artist: "Blab" },
{ title: "Something strange and badly formatted without any artist" },
{ title: "Goodnight to midnight", artist: "shirotokuro" }, // Probably impossible with some kind of AI
{ title: "Irrationality" artist: "Victor Love" }
]
You can use this regex that captures the title and artist part as you described in your post.
^([^-[\]()\n]+)-* *([^[\]()\n]*)

JS Code demo,
const songs = ["Lophelia -- MYTCH [Acoustic Prog-Rock/Jazz] (2019)",

"Lophelia -- MYTCH [Acoustic Prog-Rock/Jazz]",
"Death - $uicideboy$",
"SNFU -- Joni Mitchell Tapes [Punk/Alternative] (1993)",
"Title - Aritst (2000)",
"Something strange and badly formatted without any artist [Classical]"]
songs.forEach(song => {
m = /^([^-[\]()\n]+)-* *([^[\]()\n]*)/.exec(song)
console.log("Title: " + m[1] + ", Artist: " + m[2])
